We are getting this message when trying to run Config Wizard
verifying that the was service is available failed
you can try and temporarily disable your Anti-virus and re-run the config wizard to make sure your Antivirus software package is not preventing you from running the config wizard or causing your environment to perform slowly or unresponsive.
Try once more, there was a problem with api availability
Just because it's important - especially "these days" - I want to clarify the "turn off anti-virus" instruction.
Unclutch your pearls, pull up your fainting chair, grab a restorative drink, and hear me out: ONLY DURING INSTALLATION, FOLKS!! As soon as the install is over, you should (of course) turn AV back on. And do a scan. But AV will 100% bork (that's a technical term.) your install.
Honestly, there are TWO big stumbling blocks with installs that I and other engineers see:
1) people install using an account other than local admin. ONLY install SW with local administrator. Period. Not domain admin. Not "Bob who is part of the local admin group". Actually log in/change context to local administrator and run the installer from there.
2) turn off AV and anti-malware DURING the install. Once you've installed, turn that sh... tuff back on.
There are other install/upgrade tips, but those two seem to be most relevant, uh, "these days".
